// ── Unified fetch hook (Lesson Shortener + Stories Shortener + Free Max) ──
//
// ROOT CAUSE OF PREVIOUS CONFLICT:
// _installFakeSuper() injected a <script> into page context that replaced
// window.fetch AFTER _lsInstallHook() already wrapped unsafeWindow.fetch.
// Result: the page-context fetch (used by React/Duolingo) was the FakeSuper
// hook, which called the *original* fetch — completely bypassing the LS/SS
// hook that lived only in the sandbox layer.
//
// FIX: One single <script> injection handles ALL three features together.
// The sandbox LS hook still runs for the /2023-05-23/sessions POST (which
// goes through GM_xmlhttpRequest anyway), but the page-context hook covers
// the GET intercepts that React actually uses.
